본 발명의 일 실시예에 따르면, 내측부재와 외측부재가 전동체를 통해 상대회전 가능하게 연결되는 휠베어링이 제공된다. 본 발명의 일 실시예에 따르면, 휠베어링의 단부에는 외부의 이물질이 유입되거나 내부의 윤활유가 누출되는 것을 방지하기 위한 씰링부재가 구비될 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재는 기본 몸체를 형성하는 프레임과 프레임에 부착되는 탄성 씰링부를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재의 반경방향 외측부에는 반경방향 외측으로 돌출하여 형성된 오버몰드부가 구비되고, 오버몰드부는 휠베어링의 조립방향에 위치하는 면에 조립방향을 따라 이동할수록 직경이 감소되는 경사부를 포함하도록 구성될 수 있다.

    Provided is a wheel bearing connecting an inner member and an outer member using a rolling element to be relatively rotatable. According to one embodiment of the present invention, a sealing member is provided to prevent leakage of inner lubricant or entrance of external foreign substances at the end part of the wheel bearing, and comprises: a frame forming a basic body structure; and an elastic sealing unit attached to the frame. In addition, an overmold unit is prepared to protrude radially outwards from an outer lateral unit of the sealing member in a radial direction and comprises an inclined unit, of which a diameter reduces as moving along an assembly direction of the wheel bearing, on a surface where the assembly direction is located. The wheel bearing reduces risk of damage on the sealing member during assembly and improves sealing and assembling performance.
